TC9324F

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9324F Single-Chip DTS Microcontroller (DTS-20) TC9324F The TC9324F is a single-chip digital tuning system (DTS) microcontroller incorporating a 230 MHz prescaler, PLL, and LCD driver. In addition to a 20-bit IF counter, an 8-channel, 8-bit AD converter, two types of serial interface, and buzzer function, the TC9324F offers a range of functions required for DTS, including an interrupt function, an 8-bit timer-counter, and an 8-bit pulse counter. In addition, the LCD driver features six modes combining 1/4, 1/3, and 1/2 duty and 1/2 and 1/3 bias. This product is suitable for use in a wide variety of DTS systems, from automobile to home audio, including compact stereo systems. Features Weight: 1.6 g (typ.)
